LNA

Multiband LNA Modules for Mobile Devices

In mobile devices high system sensitivity enhances the end customers’ usage experience by maximizing data rate and ensuring good reception quality even far away from the base station. The best way to improve the system sensitivity is to add an LNA in the receive path. An LNA can suppress the noise contribution coming from the analog RF front-end, the transceiver and mitigate line loss. Therefore, the system sensitivity can be improved by several dB. We offer a broad product portfolio of MMIC LNAs for 2G/3G/3.5G/4G/4.5G applications (e.g. GSM/EDGE, CDMA, UMTS, HSPA, LTE, LTE-Advanced). Our LNA portfolio covers all commonly used band(s) or band combinations with 1-band, 2-band, 3-band, 4-band LNA(s) in the frequency range from 700MHz up to 2800MHz. These MMIC LNAs boast the following salient features:

LNA circuit with 2 or 3 digitally switchable gain levels enabling operation with either good noise performance or under high jammer/interference environment
